More Randomness for Sunday

The many of you who guessed it was a fountain pen nib were absolutely right. Good job.

Someone suggested that I show full-sized images of mystery picture photos which I will try to start doing once I run out of my current backlog.

Some of you might be wondering exactly how much the microscope magnifies so I stuck this metal ruler underneath it. I never use the 10x, so I decided to only show you at 60x (top) and 200x (bottom). The black marks are millimeter marks so as you can see, 60x is about 3 millimeters and 200x is about 1 millimeter.







A down feather from a feather pillow, probably goose down, shown here at 60x, 200x and 200x with the blacklight.





That's right, I shed blood for this blog! Here's some of it, first drying and coagulating and then dried out, all at 200x.



Finally, the mystery picture at 60x! What could it be? Leave a guess in the comments section.
